- The total population of children born in 1971 and living in Gothenburg, Sweden, by the end of 1977 was screened in order to estimate prevalence figures for various neurodevelopmental disorders. Ninety-four percent of all children assessed attended public preschools. Questionnaires aimed at detecting perceptual, conceptual, motor, and attentional deficits were completed by preschool teachers for 72% of children in these schools. Samples of children with and without problems on the questionnaire were given neuropsychiatric examinations. National registers were searched to identify mentally retarded children not in public preschools. The total population frequency figure for unequivocal mental retardation was almost 1% with an additional 1% of the total population deemed to be of borderline intelligence.

- A total population study of 4797 six-year-old children attending the public preschools in the city of Göteborg (Gothenburg) has been carried out. A questionnaire with 34 questions about MBD-related problems was distributed to all pre-school teachers. Three thousand four hundred and forty-eight questionnaires were completed. Factor analysis of the questionnaire and empirical results from a pilot study provided the basis for selecting for further study children with pre-school signs and symptoms suggestive of MBD. Neurological, psychiatric and psychological assessment of 82 children with, and 59 children without, pre-school symptoms of MBD revealed that in the index groups 41% of the children, and in the control group 3% of the children, had MBD. Extrapolation procedures gave a total population frequency of 1.2% with severe MBD and a further 5.9% with mild-moderate MBD. A very large questionnaire refusal rate (28%) is discussed. The relevance of the calculated frequency figures, especially as regards the mild-moderate MBD category, cannot be properly evaluated until long-term follow-up has been completed.

Tidskriftsartikel (refereegranskat)abstract
- This study presents the results of neurological assessments of a representative sample of seven-year-old Swedish children with perceptual, motor and attentional deficits and their controls (N = 141). Among those children diagnosed as suffering from minimal brain dysfunction (MBD), the majority showed neurodevelopmental deviations indicative of the "clumsy child syndrome'. However, 20 per cent had slight signs of choreoathetosis, diparesis, hemiparesis or ataxia. Other associated neurodevelopmental deviations are considered. The correlation between neurological findings and background factors is discussed: the MBD group had higher scores for various "organic' background factors than the comparison children, and the children with neurological syndromes had somewhat higher scores than the remaining children with MBD. The difficulties in distinguishing MBD from mental retardation, cerebral palsy and childhood psychoses is clearly illustrated. Long-term follow-up will indicate the prognostic significance of these findings.
